Ultra Fractal is an (
Windows only, unfortunately) awesome
fractal creating program. It is very
easy to use, and takes very little
time to learn the different
features it has, such as many
layers
per fractal,
customized
formulas and
color schemes, and different
transcriptions, to make your fractal
swirled,
kaliedescoped,
tiled,
radialed,
et cetera.
For a free shareware trial version of Ultra Fractal and some examples of what can be done with the program, visit the official website at www.ultrafractal.com. If you download it, be sure to also get more formulas for it, obtainable at formulas.ultrafractal.com. Not only is it a good *gag* learning tool, it's damn fun and can make pretty pictures easily. If you like computer graphics, I think you'd like Ultra Fractal.
